struct basic_common_reference<TTuple, UTuple, TQual, UQual>;
(since C++23)

The common reference type of two tuple-like types is a std::tuple consists of the common reference types of all corresponding element type pairs of both types, where the cv and reference qualifiers on the tuple-like types are applied to their element types.


the following constraints need to be satisfied:
